ANALISIS METODE SACK GABION, GABION MATTRESSES, DAN RIPRAP UNTUK MENCEGAH PENGGERUSAN PADA PILAR JEMBATAN

Abstract

Abstract: Method to prevent scouring, which is popular, is riprap, sack gabion, and gabion mattresses. The aims of this research are to analyze: (1) effectively installation patterns, (2) effectively dimensions, and (3) significance level. Method for analysis use descriptive analysis non dimensional. Results of research: (1) effective pattern installation is installing the structures at the face of pier and above river bed, (2) Dimension of the structures indicate that ever greater of the structures more effective to prevent scouring with optimum dimension is p/t = 4 (p = length and t = high), and (3) the structures give good performance to prevent scouring.
